A further object is to provide a pneumatic tire wherein means isprovided to sustain the tire should one or more of the inflatablesections be punctured whereby the repair of the punctured section maybedelayed until convenient.

Also one of the principal objects of the invention is to provide a tirewhich may ment ofthe invention, the numeral Vwith approximately berepaired without the lexercise of unusual skill and which is practicallyblowout proof. A further object is to provide a tire which is capable of4long wear, which is .neat in appearance and cheap to manufacture..

Other objects and advantages will be ap parent during the course ofdescription.y

In the accompanying drawing forming a part of this application and inwhich like numerals are employed Ato designate like parts throughout thesame,

Figure V1 is a vertical sectional y,view through the improved tire,applied,

Figure 2 is an enlarged detail transverse sectional view through theimproved tire.

In the drawing wherein for thepurpose of illustration is shown a'preferred embodi- 5Ydesignates a rim about which a casing or shoe 6 ofthe usual construction is arranged.

Figure 1 shows a plurality of endl blocks 7 arranged .in spaced relationabout the rim 5 and defining a plurality of cells for the the 'followingreception of inflatable arcuate tube sectionsV 8, This gure alsoillustrates that the 0p-v posite 'ends of the end blocks 7 are formedsemi-spherical recesses the rounded ends of the for' the reception ofBynreason of this inflatable tube sections 8.

construction, the tubes whenV properly `inflatedwill com letely fill thecells formed Y Vbythe endy bloc S17 and the fabric cover 9.

t In"manufacture the end blocks'7 are` ar` ranged 1n a ng and the'fabriccover -9fi's then securely wrapped about andk attached to th fwd Yblocks7g so as to maintainlthe .blocks 1nvr spaced relation aty all times.j

to 'define'tapered pockets for the'reception of y rubberifiller orspacer plates 11. Y Theplates Y 11 are formed with openings 12 forthekre'- ception of the valve stems 13 of theseveralk sections and byreference to Figure v1 it will be see that each filler plate is securelyand positively held in position by a cover strip 14 of metal'or kothersuitable material. VThe ends of the metal cover strips are formed withapertures 16 forjthe reception of stud bolts. 17 by means of which thecover strips may be held in position. Wing nuts 18 are Vthreaded on thestud bolts 17 and may be quickly detachedl without the aid of a Y wrenchor other tool when it is desired yto gain access to one of the tubes.However the stems 13 yextend ythrough the ymetal cover. strips so thatthe tubes may be indii vvidually inflatedwithout detaching the coverstrips.

The numeralQ designates a detachable disk secured at its periphery totherim 5 bv'suitable fastening devices and it might be stated that therim is' permanently carried by an inner disk and has detachableconnection .withV the outer disk. By reason yof this construction theinner and outer disks effectively conceal the wingl nuts and otherfastening devices and also protect the parts from dust.

, In use the several tube sections are separately inflated to about v65pounds pressure, and the disk 20`is applied so as to conceal the valvestems, the Wing nuts and the like. `If one or more of Y thesections arepunctured the remainingsections and t-he filler blocks or endl blocks 74will sustain thewheel until such time as is possible or convenienttomake the necessary repair. The collapse of only one section willnotnoticeablyV impair the riding qualities of the vehicle or damage-they wheel. Of course the end sections may be Y of `rubber or otheryieldable material.V of suiicient strength to support the load withoutyielding to an; unnecessary extent.

When it is Vdesired to renew or repair one of the pneumatic sections itis merely necessary to turn the Wheel until the punctured section ispositioned a proper distance above the ground. The employment of a jackor other lifting means is unnecessary, The strip 14 and the plate 1l`may be removed and the damaged pneumatic section is then removed andthe necessary repair made. It is believed to be obvious that after therepaired section has been reinserted in the proper cell the members l1and 14e are again applied. 4

Attention is specially directed to the fact that the removal of onesection will not inl anyway disturb the other sections, as all the endblocks are held against circumferential movement by the fabric covering9.

Also the air pressure Within the tubes is 20 insufficient to cause ablow-out, even if the tire is at any time subjected to la substantialstrain or an abnormal strain.

A tire constructed in accordance with this invention permits the case towear entirely through so that the cost of maintenance is reduced to aminimum.

Having thus described the invention, what is claimed is: Y

A tire comprising a casing, an annular series of spaced yieldable 'endblocks having,l

recessesJ and separate pneumatic tube sections confined between saidblocks and havingrounded ends yreceived in said recesses, and a coveringsurrounding` said end blocks and said pneumatic tube sections and being`permanently connected to said end blocks whereby to maintain the blocksin spaced relation.
